• Tom Stoneham is Professor of Philosophy and Head of the Philosophy Department at the University of York. He is the author of Berkeley's World (Oxford University Press, 2002) and numerous papers on a wide range of topics, including perception, self-knowledge, time, and modality, as well as many aspects of Berkeley's philosophy. He is currently working on a solution to the hard problem of consciousness.


Berkeley thinks that we only see the size, shape, location, and orientation of objects in virtue of the correlation between sight and touch. Shadows have all of these spatial properties and yet are intangible. In Seeing Dark Things (2008), Roy Sorensen argues that shadows provide a counterexample to Berkeley's theory of vision and, consequently, to his idealism. This paper shows that Berkeley can accept both that shadows are intangible and that they have spatial properties.
